MFC does not allow to trap all the events on the CButton control but some commonly used events like BN_CLICKED and BN_DOUBLECLICKED and so to trap a right mouse button events on a CButton MFC you need to derive a new class from the CButton.
MyButton.h
MyButton.cpp
Now in your Dialog class you need to trap the Message that your CMyButton passes. The message passed is NM_RCLICK and you capture it as
Your member function must be declared with the following prototype:
afx_msg void memberFxn( NMHDR * pNotifyStruct, LRESULT * result );
afx_msg void OnRClicked( NMHDR * pNotifyStruct, LRESULT * result )

class CMyButton : public CButton
